Traci Darnell is a Physician’s Assistant, from Fort Worth, Texas. She earned her undergraduate degree at Southern Nazarene University in Bethany, Oklahoma. She completed the Physician Assistant program at Baylor University. The PA program took 2 years, 3 months of additional schooling after a Bachelor’s Degree.

After Traci’s husband, Dr. Brian Darnell, completed medical school in Texas, the couple moved to Casper Wyoming, for his residency program. Moving to Oregon, the couple missed Wyoming, and hoped to come back. When the position opened up at JCHC, they were happy to relocate.

The decision to have a PA work in our clinic was an easy one. Traci is skilled in treating people, and has been a practicing PA since 2000. A Physician Assistant is someone who can see and treat general patients in the clinic. She works alongside our doctors in diagnosing and treating illness.

I like the broad scope and variety of Family Practice, but I still have the flexibility to be with our family when I need to be.

Traci and her husband, Brian love the Wyoming outdoors. They are members at the YMCA, play musical instruments and volunteer in the community. She enjoys wildlife photography. The couple has 2 children who keep them busy.
